1 Claim.

This invention relates to a clamp designed primarily for use in holding sections of an eaves trough properly assembled relative to each other while being soldered.

As is well known to those skilled in the art, considerable difficulty heretofore has been experienced in holding the sections of an eaves trough properly alined preparatory to the soldering operation.

An object of the present invention is to provide a clamp which will tightly engage the sections adjacent totheir lapping ends but will at the same time leave exposed a considerable portion of the inner or concave side of the joint so that solder can be applied thereto in sufficient quantities to hold the sections assembled in proper alinement after the clamp has been removed and during the completion of the soldering operation.

A further object is to provide a clamp of this character which is simple in construction and can be applied readily to and removed from the trough sections.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claim, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as. claimed.

In the accompanying drawing the. preferred form of the invention has been shown.

In said drawing Figure 1 is a plan view of portions of two sections of a trough held properly assembled by the clamp constituting the present invention.

Figure 2 is a section on line 2'2, Figure 1.

Figure 3 is a section on line 33, Figure 1.

Referring to the figures by characters of reference, l designates an arcuate base formed of I sheet metal of heavy gauge and provided along one edge with a laterally extended flange 2 the outer edge portion of which is extended upwardly as at 3 so that an angular recess 4 thus is provided by the flange.

Formed integral with the opposed side portion of plate I is a laterally extended flange 5 having its outer portion extended upwardly as at 6 and merging into downwardly and inwardly bent portions 7 providing spaced sleeves for holding a pintle 8. This pintle, in turn, is engaged by spaced sleeves 9 extending from the outer edge of a flange I0 located along one edge of an arcuate inner clamping plate II the opposed edge of which has a laterally extended flange l2. An opening I3 is formed in the inner clamping plate ll adjacent to the center thereof and extends to points spaced from flanges I0 and I2 distances substantially equal to the height of the upturned portion 3 on flange 2.

Brackets M are extended downwardly from flange 2 and are pivotally engaged by angular levers 15 each of which has a handle I6 extend- 10 ing therefrom. r

The outer clamping plate I and the inner clamping plate II are so proportioned as to fit snugly upon the outer and inner surfaces respectively of trough sections T. When they are thus 1 located, as in Figure 3, the beads B along the edges of the trough sections will rest on the flanges 2 and 5 respectively and the flanges l0 and [2 will overlie these beads and bear upon them. The inner clamping plate II will engage 20 the inner or top surfaces of the trough sections T and is to be so located that the opening I3 will expose the end portions of the trough sections where they lap as indicated at L in Figure 2.

After the sections have thus been engaged 25 by the clamp members, the levers l6 are swung into the position shown in Figure 3 so that they will overlie the flange l2 and hold plate I l against swinging movement about its pintle 8. Consequently the two trough sections will be tightly 30 gripped and while they are thus held, solder can be applied to that portion of the joint exposed through the opening I3. Following the application and hardening of the solder, lever I6 is swung away from the positions shown in Figures 35 l and 3 so as to release flange l2. Plate H is then swung upwardly about pintle 8 so that the connected trough sections can be separated from plate I. Enough solder will have been applied,

however, to hold the sections against relative 40 movement and thereafter additional sold-er can be applied to the outer surfaces of the trough sections at the joint and the application of solder soldered, said device including an outer clamping plate of such width and shape as to provide a broad seat for the meeting ends of the sections to be joined, a single inner clamping plate shaped and proportioned to fit snugly upon the inner faces of both of the assembled trough sections and hingedly connected along one edge to the outer plate, there being an aperture in the central portion of the inner plate through which 10 the lapping portions of the sections gripped by said plate are exposed for the application of solder, and means carried by the outer plate for detachably connecting said plate to the inner plate at opposite sides of the apertured portion of the inner plate to bind said plates upon the assembled sections, said means including an operating lever movable to position above the plates when in clamping position.
